# push-hotfix.sh — 推送 H5 热更新补丁到 Gitea
#
# 用法:
#   ./push-hotfix.sh 7 stable        # 只更新 stable 渠道
#   ./push-hotfix.sh 7 all           # 更新全部三个渠道
#   ./push-hotfix.sh 7 beta nightly  # 更新指定渠道
#
# 流程:
#   1. 创建 ota/h5/index-v{VER}.html（如果不存在则从模板生成）
#   2. 计算 SHA256
#   3. 更新 ota/h5-manifest-{CHANNEL}.json
#   4. 如果是稳定版，更新 ota/version.txt
#   5. git add + commit + push
